AbstractUrbanization is a major driver of natural habitat reduction and fragmentation. Yet, reported urban-related impacts on species richness are highly variable among studies, possibly because of differences in spatial grain. To better understand the scale-dependent impacts of urbanization on species richness, we focused here on birds in a tropical region and used a stratified sampling design with multiple spatial grains.

1 INTRODUCTION The spatial distribution of an organism is crucial for its successful establishment in the ecosystem. Individual fitness and survival are expected to increase with selection of sites with low predation risk and reduced competition (Huey, 1991; Vollrath, 1987). Structurally complex habitats may increase food availability, provide shelter against predators and refuge from climatic harshness and supply alternative resources (Norbury & Overmeire, 2018; Warfe & Barmuta, 2004).
